Explain what it means to say that a diploid organism has two alleles of a particular gene.
Explain how the two alleles compare with respect to their DNA sequence if the alleles are (a)
homozygous or (b) heterozygous.
Compare and contrast: phenotype and genotype.
Explain how monozygotic (identical) twins who start out with the same genotypes can differ in
